Abstract: A thermal head includes a substrate; a heat generating section disposed on the substrate; an electrode which is disposed on the substrate and is electrically connected to the heat generating section; and a connector including a fixing ping electrically connected to the electrode, a movable pin which holds the substrate between the movable pin and the fixing pin, and a connection pin which connects the fixing pin and the movable pin. The movable pin includes a movable section which is bent or curved and a contact section making contact with the substrate. The movable pin is disposed so as to protrude from the connection pin beyond the fixing pin. The contact section is located closer to a connection pin side than a tip end of the fixing pin.

Abstract: [Object] To provide a thermal head having improved sealability.[Solution] A thermal head X1 includes a substrate 7, a heat storage layer 13 disposed on the substrate 7 and including a bulging portion 13a, heating elements 9 disposed on the bulging portion 13a, a protective layer 25 disposed on the heating elements 9, and a covering layer 27 disposed on the protective layer 25. The covering layer 27 includes a first portion 27a disposed apart from the bulging portion 13a, and a second portion 27b disposed between the bulging portion 13a and the first portion 27a. The height of the second portion 27b from the substrate 7 is smaller than the height of the first portion 27a from the substrate 7. Thus, the sealability of the thermal head X1 can be improved.

Abstract: A thermal head includes a substrate; a heat generating section disposed on the substrate; an electrode electrically connected to the heat generating section; a cover layer which covers part of the electrode; a pad electrically connected to the electrode; and a joining member electrically connected to the pad. The cover layer includes a first portion and a second portion which is smaller in thickness than the first portion. The second portion is placed on the pad. The pad has a convexity which exposes from the second portion. The joining member is connected to the convexity.

Abstract: A thermal head includes: a substrate; a thermal storage layer disposed on the substrate and having a ridge portion; heat generating portions disposed on the ridge portion; and electrodes which are disposed on the substrate. At least one of the electrodes has a first corner portion at which a side surface and an upper surface intersect, more upstream in the conveyance direction of the recording medium than the top portion of the ridge portion. In a cross section of the thermal head, an inclination angle of an imaginary line which connects an intersection point of an imaginary line which hangs downward from the top portion (13b1) of the ridge portion and the substrate, with the first corner portion, is 75° or less from the substrate. Thus, printing residue is less likely to adhere to the thermal head.
